[PATCH 0/1] [SRU X/Z/A] Fix gigabits ethernet issue on Dell TB16

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1667750

[Impact] 
Dell TB16 docking station has issue to use gigabit ethernet. The ethernet
will disconnect unless it's changed to 100Mb/s.

[Fix]
ASMEDIA wrote a quirk to change the XHCI host flow control ability.

[Test Case]
Download some big files from the web.
User confirms the patch fixes the issue.

[Regression Potential] 
This patch only effects ASMEDIA's ASM1042A.
The regression potential is low, also limited to the specific device.
